NEW YORK -- Being an actuary, calculating statistics to determine probability and risk, is the best job to have in 2010, while working on an oil rig as a roustabout is the worst, according to a study released on Tuesday.

In the same town there lived a Negro, named Henry Smith, a well-known character, a kind of roustabout, who was generally considered a harmless, weak-minded fellow, not capable of doing any important work, but sufficiently able to do chores and odd jobs around the houses of the white people who cared to employ him.
